  • Objectives : The aim of this study was to investigate the effect for allergic-inflammation of Fritillariae Thunbergii Bulbus (FTB) on HaCaT cells and RBL2H3 cells. Methods : To investigate the effects of FTB for anti-inflammation in HaCaT cells, the cells were pretreated with FTB for 1h and then stimulated with $TNF-{\alpha}/IFN-{\beta}$ for 24h. Then thymus and activation-regulated chemokine (TARC) and Macrophage-derived chemokine (MDC) levels were analyzed with ELISA kit. Also to investigate the effect of skin barrier protein, the cells were treated with FTB of various concentrations, and then cells were harvested, expressions of skin barrier protein were measured with RT-PCR. To investigate the effects of FTB for anti-allergy in RBL2H3 cells, the cells were pre-treated with FTB for 1h, and then stimulated with A23187 for 30 min. ${\beta}$-hexosaminidase, IL-4 and $TNF-{\alpha}$ were measured using cultured media. The cells were harvested to analyze the mechanism of the effect for FTB via Western blot. Results : FTB did not show cytotoxicity in HaCaT and RBL2H3. In HaCaT cells, FTB significantly suppressed the expression of TARC, MDC at a dose-dependent manner and markedly increased formation of the skin barrier proteins. In RBL2H3 cells, FTB decreased release of the ${\beta}$-hexosaminidase, IL-4 and $TNF-{\alpha}$ in RBL2H3 through inhibition of the phosphorylation of JNK and p38, which are include in the signaling mechanism of MAPK Conclusion : These results indicate that FTB has an anti-inflammatory effect on the allergic response through blocking MAPK pathway. This suggest that FTB could be a therapeutic agent for allergic response.

  • Objectives : Recently, research has been actively conducted on the efficacy of complexes based on oriental medicine prescriptions for improving immune activity and allergies. In this study, In this study, we aimed to examine the effect of Angelica gigas Nakai and Corni fructus extract (AC), medicinal herbs, among candidate drugs derived through preliminary experiments with various components of oriental medicine prescriptions for allergies, on allergies in RBL-2H3 cells. Methods : We evaluated the effect of the ethanol extract of Ulmus on the allergic inflammatory response in anti-DNP-IgE activated DNP-HSA in RBL-2H3 cells. Cell toxicity was determined by WST-1 assay and the markers of degranulation such as beta-hexosaminidase, histamine, TNF-α and IL-6 production of inflammatory mediators and FcεRI-mediated expression. Results : The results showed that treatment with AC extract (20, 40 and 80㎍/㎖) noncytotoxic levels and significantly inhibited the release of β-hexosaminidase, histamine and the production of TNF-α and IL-6 in RBL-2H3 by the antigen stimulation. Conclusions : These results indicate that AC extract exhibits anti-allergic activity through inhibition of degranulation and inhibition of inflammatory mediators and cytokine release. These findings suggest that AC extract may have potential as a prophylactic and therapeutic agent for the treatment of various allergic diseases.

  • During the screening program to discover antiatopic agents from herbal formulas, we investigated the inhibitory effect of Hwangryunhaedoktang (HT) on passive cutaneous anaphylaxis and oxazolone-induced mouse ear dermatitis. HT significantly inhibited PCA reaction in mice at doses of 50 and 200 mg/kg with inhibitory activity of 31 and 53%, respectively. HT at concentration of 0.05 and 0.1% inhibited ear swelling by 23 and 46% at 16 days in oxazolone-induced mouse ear dermatitis. Both HT with anti without human intestinal microflora showed potent inhibitory activity on the ${\beta}$-hexosaminidase release induced by IgE. Based on these findings, HT may be a usable agent for skin disorder contact dermatitis.

  • We studied the effect of methanol extract of Carpopeltis affinis (CA) on atopic allergic reaction. CA dose-dependently inhibited interleukin (IL)-8 and tumor necrosis factor (TNF)-$\alpha$ secretion from the PMA- plus A23187- stimulated HMC-1. CA also dose-dependently inhibited the histamine and $\beta$-hexosaminidase release from mast cells. CA had no cytotoxic effect. (omitted)

  • 제 1형 과민반응은 비만세포에 의해 매개되는 알러지 반응으로서, 예기치 못한 알러젠에 의해 비만세포가 활성화 되어 탈 과립 되면서 히스타민등과 같은 여러 가지 매개체들을 분비하면서 과도하게 면역반응을 유도하게 된다. 주박(Korean rice wine lees)은 청주, 약주 등의 술을 걸러내는 과정에서 생기는 양조 부산물로서, 최근들어 청주를 걸러내는 과정에서 생기는 술 지게미의 생리기능에 대한 연구가 활발하게 진행되고 있다. 본 연구에서는 주박의 ethyl acetate (EA) 추출물을 이용하여 비만세포에서의 탈과립 억제 효과를 측정하였다. 그 결과 주박 EA 추출물이 탈과립의 표지인 ${\beta}$-hexosaminidase의 양을 농도 의존적으로 억제하는 것을 관찰하였고, 이러한 탈과립억제 현상이 다양한 사이토카인 중 IL-3과 IL-13의 양을 감소시킴으로써 매개된다는 사실을 RT-PCR을 통해 확인하였다. 또한 쥐에서 passive cutaneous anaphylaxis (PCA)를 유도하여 EA를 경구투여 했을 때 anaphylactic 증상을 효과적으로 억제하는 것을 관찰하였다. 이러한 결과들은 주박 EA 추출물이 항 알러지 약물의 개발에 잠재적인 후보물질이 될 수 있음을 시사한다.

  • The purpose of this study was to examine the anti allergic effect in vivo and in vitro, and to observe single and four weeks repeated toxicity in mice of Bangpung-galgeun-tang (BGT). We investigated anti DNP IgE-mediated passive cutaneous anaphylaxis in rodents and compound 48/80-induced active systemic anaphylatic shock in mice after oral administration with BGT of 0.4 g/kg and 0.8 g/kg for 8 days, and also examined MTT assay, ${\beta}-hexosaminidase$ activity, IL-4 and $TNF-{\alpha}$ from RBL-2H3 and $TNF-{\alpha}$ from Raw264.7 after pre-treatment with BGT of 0.25 mg/ml, 0.5 mg/ml, 1 mg/ml and 2 mg/ml. To ascertain safety and toxicity of BGT, we divided into single and four weeks repeated administration test. In single test, three groups were administrated different dosages and routes (2 g/kg/i.p., 4 g/kg/i.p. and 15 g/kg /p.o.) of BGT, and in four weeks repeated test, 0.8 g/kg BGT was administrated. Control groups were administrated with only saline according to on Korean Food and Drug Administration, respectively. We observed attentively motality, abnormal clinical sign, body weight change, organ weight, AST and ALT of mice after BGT administration. BGT inhibited passive cutaneous anaphylaxis and active systemic anaphylatic shock by oral administration. All the concentrations of BGT from 0.25 to 2 mg/ml didn't have an effect on cell viability and cytotoxicity. In RBL-2H3, ${\beta}-hexosaminidase$ release, IL-4 and $TNF-{\alpha}$, and in Raw264.7, $TNF-{\alpha}$ were significantly reduced by treated all concentrations of BGT. During toxicity experiment period, there was no difference in body weight change, organ weight, AST and ALT among different dose groups. Death were found 3 mice from day 2 to day 3 in single test i.p. group. (2 g/kg, 4 g/kg). Several individuals of single test i.p. group were observed that decreased locomotor activity, exophthalmos, bloodshot eyes, loss of eyesight and so on in early period after administration. But there was no difference in clinical signs among p.o. group. These results indicate that BGT have inhibition effects on allergy and suggest that no observable effect level of the test orally administration was considered to be more than 2 g/kg in mice under the conditions employed in this study.

  • This study was to evaluate the effect of Samjayangchin-tang (STYCT) on mouse Th1 and Th2 cells' differentiation and ovalbumin (OVA)-induced allergic inflammation. The proliferation of mouse CD4 T cells and the secretion of Th1/Th2 cytokines under the influence of STYCT extract were measured as well as the amount of ${\beta}-hexosaminidase$ in RBL-2H3 cells and the levels of $TNF-{\alpha}$ and IL-6 secretion in Raw264.7 cells. BALB/c mice were orally administered with STYCT extract and simultaneously inoculated with OVA to induce allergic reaction and measure the level of total IgE, OVA-specific IgE and the production of IFN- g, IL-4, IL-5 by the spleen cells. When mouse CD4 T cell were stimulated with anti-CO3 and anti-CD28 for 48 hours in various concentrations of STYCT extract, it decreased proliferation of CD4 cells. CD4 T cells under Th1/Th2 polarizing conditions for 3 days with STYCT resulted in mild decrease of IFN- g in Th1 cells and significant decrease of IL-4 in Th2 cells. STYCT extract had a dose-dependent inhibitory effect on antigen-induced release of ${\beta}-hexosaminidase$ in RBL-2H3 cells. Treatment of STYCT extract on LPS stimulated Raw 264.7 cells showed dose-dependent decrease in IL-6 production. Oral administration of STYCT extract on OVA-induced allergic mice showed an inhibitory effect on the levels of total serum IgE and OVA-specific IgE by 53% and 44%, respectively. Culture of spleen cells with OVA resulted in significant increase of IFN- g by 54% and significant decrease of IL-4 and IL-5 by 42%, and 29%, respectively. The results show that STYCT does not strongly induce mouse T cells to transform into Th1 or Th2 but it has an anti-allergic effect in vitro, and that it also corrects the unbalance between the reactions of Th cells in allergic diseases.

  • 결명자(Cassia obtusifolia) 및 포공영(Taraxacum platycarpum), 유근피(Ulmus macrocarpa)로 제조된 생약재 추출혼합물이 in vitro와 in vivo상에서 아토피 피부염에 미치는 영향을 실험하였다. HMC-1 cell을 이용하여 비만세포의 $\beta$-hexosaminidase 방출량을 측정한 결과, 단일 추출물보다 추출복합물이 탈과립을 억제하는 효과가 우수한 것으로 측정되었다. 그리고 HMC-1 cell에서 PMA와 A23187로 자극하였을 때 생성되는 염증성 cytokine의 분비에서도 추출혼합물의 저해 효과가 가장 높게 나타났다. 아토피 질환모델인 NC/Nga 마우스를 사용하여 생약재 추출혼합물의 아토피 저감효과를 측정한 결과, 진드기 추출물에 의해 발진된 마우스의 귀두께 및 조직학적인 부종 관찰을 통해 생약재 추출혼합물 농도가 증가함에 따라 대조군에 비해 귀 두께 및 부종의 감소가 관찰되었다. 또한 마우스의 혈중 IgE 농도와 이와 관련된 cytokine의 농도를 측정한 결과, 생약재 추출혼합물 투여농도가 증가함에 따라 IgE의 농도가 유의적으로 감소하였고, IgE의 과발현을 유도하는 IL-4의 분비 억제 및 IFN-$\gamma$의 분비가 증가되는 것으로 나타나 생약재 혼합추출물의 섭취가 아토피 피부염 증세 완화 효과에 도움이 되리라 사료된다.

  • 간장은 한국의 전통 발효식품으로써 최근 항암 효과, 항균작용, 항산화능, 항혈전 효과 등의 효능이 보고되고 있다. 한국의 간장은 콩과 밀을 주요 원료로 사용한다. 콩의 세포벽으로부터 유래되는 다당류는 효소적 가수분해에 저항성이 있으므로, 발효가 끝난 후에도 간장에 잔존하게 되며 이것을 간장 유래 다당류(Kanjang polysaccharides, KPS)라 부른다. 본 연구에서는 산분해법과 양조법으로 제조된 시판 간장인 A~T의 20종의 투석물로부터 다당류를 제조하고, 비만세포에서 염증성 cytokine의 방출과 mRNA의 발현에 대한 KPS의 효과를 실험함으로써 항염증 효과를 조사하였다. RBL-2H3 세포에서 KPS의 처리는 histamine과 ${\beta}$-hexosaminidase의 방출을 현저히 억제시켰다. 자극된 HMC-1 세포에서 KPS의 처리는 염증성 cytokine인 IL-6, IL-8, TNF-${\alpha}$의 방출 및 mRNA의 발현을 감소시켰다. 특히, 양조간장으로부터 유래된 KPS는 산분해 간장보다 비만세포에서 우수한 항염증 효과를 나타내었다. 따라서, KPS는 알레르기성 염증반응을 억제시키는데 효과적일 것이라 사료된다.
